LEAPERS OBSTACLE.

To all whom it may concern:

Be it known that I, RICHARD LUDWIG Kni- MEL, citizen of the German Empire, residing at Benrath, near Dusseldorf, Province oi the Rhine, German Empire, have invented new and useful improvements in Leapers Obstacles, of which the following is a specification.

My invention relates to improvements in obstacles of the class which is used in gymnastics for marking the height of leaps in the exercise of leaping and its object is to provide an elastic obstacle of plain construction, easy adjustability and safety to the leaper, which may be employed not only for gymnastic exercises of men. but which may as well be used with advantage as a yielding hurdle in hurdle races, in training horses and for certain games and exercises as well as in circus and theater.

My invention consists of a pneumatic bar employed in a barrier used in leaping exer- -cises in a gymnasium as herein described and which is illustrated on the drawing herewith in which Figure 1 is a view in side elevation, while Fig. 2 is longitudinal section through one of my improved devices.

The drawing shows pair of standards from each of which points as an obstacle a hollow bar (4, preferably conical with a rounded point, of any flexible material which permits its inflation with air. In the buttend of the cone may be inserted a rigid piece of pipe 6 having on one end a flange to keep it fast in the said butt-end while the other end contains a self closing valve 0 permitting the application of an airpump and being made tight by an india-rubber ring or other suitable packing (Z. The but-t- Specifieation of Letters Patent.

end of the bar may have attached thereto a sliding piece 0 by which it is made vertically movable and adjustable on the standard.

As the drawing shows, the two bars, each filled with air, should be directed against each other thus forming one closed marking line or barrier.

Whenever a leaper or an animal during the exercise of leaping touches one or the two bars, which are soft and yielding, they will give way and at once return into their ordinary positions without swinging to and fro and without disturbing the standards which may be rigid or elastic.

I claim:

1. As an obstacle to leapers a hollow bar of flexible and airtight material, means attached thereto adapted to permit inflation with air and means permitting its attachment to a support, all substantially as described.

2. As an obstacle to leapers a pneumatic bar of flexible and air-tight material, which when inflated is substantially conical in form with a rounded point, a pipe in the butt-end ot' the cone having a flange on one end, a valve in the other end of the said pipe, adapted for the application of an air-pump, an air-tight packing and a sliding piece adapted for attachment and adjustment on a vertical standard.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

RICHARD LUDWIG KIMMEL.
